I wanted to play with AdSense so I applied for it just now and started obfuscating four letter words in my blog so Google won't think I am a porn site.

Good point. Does Google tell you that this would be a good idea?

Park is not doing such a good job as a self censor though. Three posts below in a post about broadband Google's porn buying audience will learn that Park was recently "at the receiving end of a gang-bang".

Another issue with AdSense for weblogs: The suggested adds are invariably adds for 'weblog stuff', and not the stuff you write about - if you manage to escape the blogs about blogs disease once in a while.
